21, March 27.

After inspecting Luzon for more than half a month, Karl and his party once again secretly returned to Honsavady.

In the town of Mongguan, Kachin State.

It is the secret production base of Aoba Airlines, which is built on a plain 4.1 kilometers away from the town, backed by a large mountain.

Therefore, the base is actually divided into two parts, one is placed on the open surface, and the other is embedded in the mountains, hidden by the green umbrella system and underground facilities.

The reason for this is mainly for safety, after all, it is impossible to completely cover up, after all, in the production process of the base, a large number of materials need to be in and out, and some of them must be transported in from the outside world.

Factories can be camouflaged, but roads and railways cannot be built completely underground, even if it is rainy all day, it is not a long-term solution.

If you don't put a factory on the surface here, so many vehicles in and out can be easily photographed by satellites in the sky.

Then the other party analyzes.

Boy! It's a place full of greenery, and as long as the intelligence analysts of the great powers don't get their heads into the water, they can definitely guess that there is something wrong here.

Either they are conducting unknown experiments, or they are in a secret factory.

Unless it's the kind of base with an extremely high self-sufficiency rate, a reasonable vest area needs to be arranged outside to cover up the real base.

For example, the nuclear base in Black Tiger Canyon uses a nature reserve and a lead-zinc mining company as cover.

Even with the Green Umbrella system and the technology to quickly dig into the underground, Homo sapiens has not let its guard down.

Even if the first hydrogen bomb imitating B43 could be produced around June this year, Homo sapiens still has not approved underground nuclear tests.

Because underground nuclear tests are also detected by the outside world.

Even if the formation blocks the leakage of radioactive fallout, the shock wave generated by the explosion can cause an earthquake, and the shock wave formed by a nuclear explosion earthquake is completely different from the shock wave of a natural earthquake.

Nowadays, there are many earthquake monitoring stations around the world, and it is easy to locate the location of earthquakes and analyze the anomalies of shock waves.

Homo sapiens does not plan to conduct underground nuclear tests until it has stockpiled hundreds of hydrogen bombs.

In this year's strategic plan, Homo sapiens intends to digest the two new control areas and consolidate various foundations, and does not intend to face the powers head-on.

The development of the aviation industry is one of the plans to lay a solid foundation.

……

Karl and others, who had just returned, immediately organized engineers and technicians to carry out a comprehensive transformation of the MiG-25 production line.

In the final assembly workshop.

The previously updated industrial auxiliary equipment is undergoing secondary adjustment of parameters.

Wang Haoran was a little surprised: "Chief Engineer Karl, adjust to this parameter, will it not be able to support it when it is assembled?" ”

The reason why he asked this was because the empty weight of the MiG-25 was 15 tons, and the power of the adjusted conveyor belt was only about 10 tons.

"Wang, don't worry, we have improved the material of the body, and the weight will be reduced to less than 10 tons by then." Carl explained with a smile.

"Improving materials?" Wang Haoran muttered quietly, but he was a little disappreciative in his heart.

You must know that the reason why the MiG-25 uses stainless steel materials is mainly to break through the triple speed of sound and resist frictional heat of up to more than 300 degrees Celsius.

Ordinary aviation aluminum alloy can only resist frictional heat of more than 100 degrees Celsius.

As for the latest super heat-resistant materials, Wang Haoran doesn't think that the company can buy them, these materials are the housekeeping skills of the major powers, and there is no place to buy them.

Carl saw Wang Haoran's expression, but he didn't bother to explain, because facts speak louder than words.

When the time comes, Mandalay Specialty Smelting Company will be able to provide a steady stream of new material parts and components after the production line is arranged.

80% of the weight of the MiG-25 body comes from stainless steel, which is about 12 tons, and its material composite density coefficient is 7.92.

After replacing the new material, its density coefficient drops to 3.22.

In addition to other parts, new materials will also be replaced.

At that time, the empty weight of the new MiG-25 will drop to 7.53 tons, which is about half of the previous one.

As for the engine's power, it hasn't been tested yet, but Carl knows that its power will definitely get a certain boost.

The weight of the body has decreased, the structural strength has increased, and the power has increased, and these changes add up, and the MiG-25 will definitely be reborn.

This is the synergistic effect of material advantages.

Even if it was an old model from decades ago, Karl was confident that it would be able to stand up to the active fighters of the Great Powers.

……

Mu Ziying, who also works in the base, did not participate in the transformation of the production line, but was designing the engine.

To be precise, it is improving the R15B-300 turbojet engine of the MiG-25.

After entering various parameters, a 3D model of the R15B-300 turbojet engine has been generated using an internal supercomputer built by the biochip.

Mu Ziying frowned, looked at the improved model on the screen, turned his head with some concern and asked, "Mr. Mikoyan, such an improvement will cause a large number of deflagration shocks in the combustion chamber, and the engine will be blown up directly." ”

"Wood, you call up the list of materials in the aided design system, find the internal materials in it, and you will know why I have improved it this way." Alyosha Mikoyan continued to immerse himself in his own improvement work.

Mu Ziying was stunned for a moment, and then called up the internal materials.

Then his eyes widened, even if he had a wooden personality, he was very shocked at this moment: "There is actually a material of this level?" Unbelievable ......"

He harmonizes the materials into the individual parts of the engine model, and then has the system automatically calculate the engine's extreme operating parameters at this time.

He was stunned to see the extreme operating parameters given by the supercomputer.

"Is there really such a material?"

Alyoshami, who did not raise his head, replied expressionlessly:

"All the materials on the list are available to the company, so you don't have to worry, now it's better to find a way to improve the engine! Our work is very important, the production line will be adjusted in June, and then we will send the drawings of the engine parts to the parts factory. ”

Mu Ziying took a deep breath: "I understand. ”

He looked at the engine in front of him at this time, and no longer felt that it was lagging behind, but that it would shock the world.

Calling up the new materials that could be used, he revisited them and began to replace them.

It's not a casual thing.

In other words, you can do whatever you want, but you just waste some of the performance potential of these new materials.

For example, after the use of new materials, the thickness of the inner wall of the engine combustion chamber does not need the previous thickness, according to Mu Ziying's careful calculation, the thickness can be reduced to 63.7% of the original, and the effect is enough to withstand long-term deflagration shock.

For an airplane, the dead weight of the fuselage is often comparable.

Reducing dead weight is increasing the payload and range of the aircraft.

Mu Ziying didn't quite understand what the company was doing when it acquired the production line of the MiG-25, a classic fighter, but now he has come to his senses.

With the blessing of these new materials, the production line of MiG-25 is the most cost-effective choice.

After all, the cost of advanced fighters in service in various countries is ridiculously high, let alone the purchase of production lines.

Small countries simply cannot afford the active production lines of advanced fighters of the Great Powers and are not eligible to buy them.
